Nares two of them, right and left; the entry way into the nose
Septum cartilage and bone that separates the nose into right and left sides
Turbinates cartilages that swirl the air; done so it will increase contact with the inside of the nose to heat, humidify, and filter it
Vascular large amount of blood vessels so that it will heat the incoming airs
Mucus helps to humidify and trap dirt, debris, and pathogens from the air
The lower respiratory tract starts at the trachea and ends at the alveoli.
The trachea divides into right and left bronchi, which enter the right and left lungs.
From the bronchi, the airways divide and become progressively smaller.
There is a bronchi for each lobe and segment of the lungs.
From the segmental bronchi, the airways become very small (bronchioles) and end in microscopic air sacs called alveoli (singular is alveolus).
Gas exchange occurs at the level of the alveoli.
V/Q VQ scan is an imaging test that uses a ventilation (V) scan to measure air flow in your lungs and a perfusion (Q) scan to see where the blood flows in your lungs
